It includes parts of the ancient port and city walls, with remains of three square towers and a gateway dating back to the second or third century BC.

[3] During the work carried out in 1967 for the construction of the shopping arcade in the "Centre Bourse" in the heart of Marseille, important archaeological remains were unearthed.

The extent of this discovery, which concerned the Greek fortifications of Marseille, funerary enclosures and part of the old port, necessitated the classification of approximately 10,000 m2 as a historical monument.

A garden, surrounded on three sides by the shopping centre, has been laid out to highlight the vestiges, the results of one of the most important post-war urban excavations carried out in France.

Quays that date back to Roman times are visible and are preserved over a length of 180 meters; stairs used for unloading goods can still be seen.

The oldest discoveries were made in the northwestern part and involved a portion of the north–south road which dates back to the 6th century BC.

A first rampart made up of a white limestone base from Saint-Victor surmounted by an elevation in raw clay bricks dating from the end of the 5th century BC was also discovered.

This new rampart seems to have included, like the previous one, a stone plinth surmounted by an elevation made of large blocks of tuff which replaced the raw bricks.

In the second half of the 2nd century BC, the rampart was rebuilt on a large scale, this time in blocks of pink limestone from Cape Couronne, transported by boat.

Some archaeologists of the time thought they had discovered the rampart that Crinas, a wealthy doctor from Marseilles living in Rome, had built at his own expense in the course of the 1st century.

To the east of the garden and near the gallery of the Center Bourse is a large square basin made at the beginning of the 2nd century, about 15 m on each side, in well-paired stones, comprising on the whole five courses.

On the western internal facing, anchor points and a reserved cavity in the paved ground, attest to the existence of a wheel which must have been 3 m in diameter, used to clear the alluvium carried by the water.

In the center of this terrace a square-shaped plinth was discovered carved from large white limestone: it might have been the base of an altar or statue.

The remains were recovered; they were found in lead, ceramic or bronze urns, which were then placed within stone boxes and arranged in a pit of funerary terraces.
